Hahahahahahaha! Okay then...I was all about your comment until you told her that her rant was incoherent. As if....AS IF she knows what incoherent means, you have to use key stage one English for her. I applaud your comment though really.
Unintelligible?
Incomprehensible?
Or #bekind and use 'muddled', 'unclear' or 'IT MAKES NO SENSE'...!
This is why in a way I sometimes think you should take an I.Q test to be able to have a proper public social media profile. It isn't monitored properly. And there's far too many people with dangerous and uneducated opinions spouting absolute nonsense, sometimes even dangerous information to very impressionable young people.
Kate is definitely up there with the worst!
